The brutality of this scene comes from how fast things take a turn: the conversation between Zoe and Frank, skulking around a subway station in disguise, is filled with a sense of both urgency and unease, but you're not quite sure where it's going to go.
You certainly don't expect it to go where it does, with Frank suddenly pushing Zoe - who was getting too close to the truth - in front of an oncoming train, leading to her unceremonious death. As a moment that encapsulates the power-mad world of House of Cards, and the sheer, unabating ruthlessness of Frank Underwood, this is the defining House of Cards moment, and the one most likely to leave you feeling like you've been punched in the gut.
NCTJ-qualified journalist. Most definitely not a racing driver. Drink too much tea; eat too much peanut butter; watch too much TV. Sadly only the latter paying off so far.
A mix of wise-old man in a young man's body with a child-like wonder about him and a great otherworldly sensibility.
